LEWIS WOLFLEY, OF PRESCOTT, ARIZONA TERRITORY.

DUIMP-BUCKET Application filed August 19, 1907.

To all whom it may concern:

Be it known that I, LEWIS VVOLFLEY, a citizen of the United States, residing at Prescott, in the county of Yavapai and Territory of Arizona, have invented certain new and useful Improvements in Dump- Buckets, of which the following is a specification.

My invention relates to buckets or receptacles for lowering materials and depositing or dumping them in a suitable manner, especially automatically, and has for its principal object the production of such a device particularly adapted for use in the formation of concrete piling, although it will obviously be useful for other purposes and in other connections.

The invention resides in the novel construction and arrangement of parts of an automatic dump bucket hereinafter described and claimed, and illustrated in the accompanying drawings, in which Figure l is a view in side elevation of the bucket closed, the movable part being shown open, by dotted lines; Fig. 2 is a similar view of the same, looking from left to right in Fig. 1; Fig. 3 is a plan view in section taken on line 33, Fig. 1; and Figs. 4 and 5 are enlarged details of the latch.

Referring to the drawings, A is the main body portion of the bucket, and B the lower portion. Body portion A has a diameter which increases from top to bottom, or, in other words, its walls slope outwardly and downwardly, so that the material contained in this portion will be readily discharged when released. The bucket is connected to a hoisting rope or chain in any suitable way, as by bail a.

The lower portion B is composed of sections, one at least of which is movable. I have shown these sections as two in number,

' section I) being rigidly attached to body portion A, and section I) being movably connected to the body portion by hinge 5 The walls of the lower section B preferably slope inwardly, the angle of slope of section 5 being less than that of section b. Braces or holding clips a-a are provided upon body portion A to hold the outer corners of section 7) against the strain of the load.

Lower portion B is normally held closed by a latch member 0 pivoted at 0 for vertical movement upon one of the sections, as b, and is provided with a latch piece 0 which engages a slot 0 in the nose piece Specification of Letters Patent.

c of the other section. Latch member 0 also has a trip finger c which extends downwardly beyond the end of the bucket and is adapted to contact with the surface or material at the end of the downward travel to release the latch and dump the bucket. Finger 0* has a rearward clip 0 to brace the parts when the latch is closed.

The operation of the bucket will be obvious from the drawing and foregoing description. The section Z) being in its closed position, as shown in Figs. 1 and 2, latch member C is moved to its latching position (shown in Fig. 1, and in whole lines in Fig. 2), latch piece 0 engaging the slot 0 in nose piece 0 and thereby securely maintaining section 5 closed. When, in lowering the bucket, trip finger a strikes the ground or material already deposited, latch member C is moved to the position shown by dotted lines in Fig. 2, and hinged section b swings to the position shown by dotted lines in Fig. 1. Owing to the taper of main body portion A of the bucket, the contained material is readily discharged, and is not obstructed by lower portion because of the shape and arrangement of the parts.

As this bucket is particularly designed for lowering mortar into tubes or casings to form concrete piles, it is preferably made round in plan outline; and it will be seen that section Z; slopes sufficiently to protect latch member C from contact with the tube or casing. It will also be observed that nose piece 0 in addition to cooperating with latch piece 0, protects the lower ends of the sections 5, Z), from injury by contact with the ground or previously deposited material.

It will of course be understood that my improved bucket may be used for raising, or lowering and dumping any divided or granular material, such as broken stone, coal, etc., and that modifications may be made in the details and parts shown and described without departing from the invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a dump bucket, a main body portion having an internal diameter increasing from top to bottom, a lower portion having a section movable relatively to said body portion, and means for latching said section.

2. In a dump bucket, a main body portion tapering from bottom to top, a lower portion having a hinged section movable relatively to said body portion, and means for latching I clip upon said section under which said said section.

3. In a dump bucket, a main body portion, a lower portion having a section fixed with respect to the main body portion and sloping toward the center axis of the bucket, a hinged section also sloping toward said axis and cooperating with said fixed section, and means for latching said hinged section.

4;. In a dump bucket, a main body portion the walls of which are fixed, a lower portion, the walls of which slope toward the center axis of the bucket and consist of sections of which one at least is movable with respect to the body portion for dumping, and a latch for connecting said sections.

5. In a dump bucket, a main body portion, the walls of which are fixed and slope outwardly and downwardly, and a lower portion, the walls of which slope inwardly and downwardly and consist of sections of which one at least is movable with respect to the body portion for dumping.

6. In a dump bucket, a main body portion, a lower portion comprising sections of which one at least is movable, a latch member pivoted to one section and engaging a lip on the other section, and a finger extending from said latch member .below the end of said sections to engage a stop and open the latch.

7 In a dump bucket, a body portion, a lower portion comprising sections of which one at least is movable, a latch member comprising a bar having a lateral extension pivoted to one section and engaging a lip on the other section, the forward end of said bar constituting a trip finger and the rearward end lying close to the section, and a rearward end of the bar slides when the parts are in the latched position.

8. In a dump bucket, a main body portion, a lower portion comprising sections of which one at least is movable, a latch member pivoted to one section for vertical movement and enga ing a lip on the other section, and a finger extending downwardly from said latch member to engage a stop and release said movable section.

In a dump bucket, amain body portion, the walls of which slope outwardly and downwardly, a lower portion the walls of which slope inwardly and downwardly and consist of sections, one at least of which is movable, and a latch arranged to engage a stop and release said movable section at the end of the downward travel of the bucket.

10. In a dump bucket, a main body portion, a lower portion comprising a fixed and a movable section sloping inwardly and downwardly, said movable section having a slope less than that of said fixed section and extending across the center axis of the bucket, and means for latching said movable section.

11. In a dump bucket, a main body portion flaring downwardly to facilitate discharge of the contents, a lower dumping sectlon hlnged to said body portlon, and a latch for sa d dumping sectlon.

In testimony whereof I afiix my signature,

in presence of two witnesses.
